♦ Plug-In Upgrades for Industry-Standard DG444/DG445

Maxim’s redesigned DG444/DG445 analog switches

now feature on-resistance matching (4Ω max) between

switches and guaranteed on-resistance flatness over

the signal range (9Ω max). These low on-resistance

switches conduct equally well in either direction. They

guarantee low charge injection (10pC max), low power

consumption (35µW max), and an ESD tolerance of

2000V minimum per Method 3015.7. The new design

offers lower off leakage current over temperature (less

than 5nA at +85°C).

♦ Improved r

Match Between Channels (4Ω max)

♦ Guaranteed r

Over Signal Range (9Ω max)

FLAT(ON)

♦ Improved Charge Injection (10pC max)

♦ Improved Off Leakage Current Over Temperature

(<5nA at +85°C)

♦ Withstand Electrostatic Discharge (2000V min)

per Method 3015.7

__________________Ex is t in g Fe a t u re s

The DG444/DG445 are quad, single-pole/single-throw

(SPST) analog switches. The DG444 has 4 normally

closed switches and the DG445 has 4 normally open

♦ Low r

(85Ω max)

DS(ON)

♦ Single-Supply Operation +10V to +30V

Bipolar-Supply Operation ±4.5V to ±20V

switches. Switching times are less than 250ns for t

and less than 70ns for t . Operation is from a single

OFF

♦ Low Power Consumption (35µW max)

♦ Rail-to-Rail Signal Handling

+10V to +30V supply, or bipolar ±4.5V to ±20V sup-

plies. Maxim’s improved DG444/DG445 continue to be

fabricated with a 44V silicon-gate process.

♦ TTL/CMOS-Logic Compatible
